A ball is dropped from a height of $$6$$ meters and bounces to no more than $$90$$ percent of its original height. It falls back down and then repeatedly bounces to no more than $$90$$ percent of its maximum height after the previous bounce. What is the maximum height, in meters, that the ball can reach after the $$5th$$ bounce?
A sequence of numbers $$P_1, P_2, P_3.......P_n........$$ is defined as follows: $$P_1=1, P_2=2, and P_n=4\frac{P_n-1}{P_n-2}$$ for each integer $$n$$ greater than $$2$$. What is the value of $$P_4$$

A certain experiment consists of making $$25$$ observations of the variable $$x$$, which can have integer values between $$-3$$ and $$3$$, inclusive. The experiment was performed twice, and Tables I and II represent the results. Which of the three statistics- mean, median, and mode were the same both times the experiment was performed?
The table summarizes the waiting times, in minutes, of $$500$$ patients at a certain doctor's office. Of the $$500$$ waiting times, a waiting time of $$15$$ minutes is at the $$25$$th percentile and a waiting time of $$25$$ minutes is at the $$k$$th percentile. Quantity A $$k$$ Quantity B $$50$$
